The Kingston Einbaurahmen KI 2.5 inches to 3.5 inches is functional and comes with all the necessary screws for installation. The framework could accommodate two flat SSDs superimposed. However, only the 4 screws for an SSD there and the 4 screws for installing the frame in the drive bay. More I do not need at the time and 4 screws for a second SSD can muster. Unlike other reviews, I had no problems to install this framework. It was bent or nothing difficult fit. The price of 4.20 euros is therefore properly adjusted. Was as Amazon Plus product ordered.
